彩鋼板是(shi)指(zhi)彩(cai)色涂裝(zhuang)鋼(gang)(gang)板(ban)，彩(cai)鋼(gang)(gang)板(ban)是(shi)有機涂裝(zhuang)鋼(gang)(gang)板(ban)，具有耐腐(fu)蝕性好、色彩(cai)鮮艷、外觀美觀、加工成型方便(bian)、鋼(gang)(gang)板(ban)原有強度(du)等(deng)優點，成本低(di)等(deng)特點。

　　傳統涂(tu)(tu)層分(fen)為(wei)幾類，最(zui)高(gao)級的(de)是氟涂(tu)(tu)層，幾乎可以防腐20年。一般(ban)從鋼廠以卷筒的(de)形式流(liu)通到各地。我們經(jing)常(chang)看到的(de)彩(cai)鋼板(ban)(ban)(ban)(ban)是指加工的(de)板(ban)(ban)(ban)(ban)材，厚度在50~100mm左右(you)，由中間(jian)的(de)填充材料(liao)和(he)(he)兩面(mian)的(de)彩(cai)色鋼板(ban)(ban)(ban)(ban)構成(cheng)。其中彩(cai)板(ban)(ban)(ban)(ban)厚度有(you)0.4mm、0.5mm、0.6mm等不同厚度，中間(jian)層可用聚氨酯、巖棉或泡(pao)沫塑料(liao)等。由于有(you)專(zhuan)用型材，彩(cai)鋼板(ban)(ban)(ban)(ban)建造的(de)現場(chang)建設速(su)度快(例如(ru)非(fei)典型的(de)小湯山醫院)，但強度低(di)。彩(cai)涂(tu)(tu)鋼板(ban)(ban)(ban)(ban)的(de)基(ji)板(ban)(ban)(ban)(ban)為(wei)冷軋基(ji)板(ban)(ban)(ban)(ban)、熱鍍鋅(xin)(xin)基(ji)板(ban)(ban)(ban)(ban)和(he)(he)鍍鋅(xin)(xin)基(ji)板(ban)(ban)(ban)(ban)。涂(tu)(tu)層種類分(fen)為(wei)聚脂(zhi)、硅(gui)改性聚脂(zhi)、偏(pian)聚二氟乙烯和(he)(he)塑料(liao)溶膠(jiao)。彩(cai)色涂(tu)(tu)裝(zhuang)鋼板(ban)(ban)(ban)(ban)的(de)表面(mian)狀(zhuang)態可分(fen)為(wei)涂(tu)(tu)裝(zhuang)板(ban)(ban)(ban)(ban)、壓(ya)花板(ban)(ban)(ban)(ban)和(he)(he)印刷板(ban)(ban)(ban)(ban)。
